The operation of 100pf between TX and RX-chahge CAPACITY
for min. signal in res.coil-coil compens.C=22pf to330pf.
Control witch osciloscope or amplitude detector in preamplifer output.
4.7nf that goes to 1458-ADJUST gnd fase.Change CAPACITY
1nf to100nf anb probationary with ground without metal.
Detector work with low tone for ferrous and hight tone for non-ferrous metal.
This is not kt315 stupidity fantasy.
